I certainly have thoughts. Here's the one answer. The fact is, you're hearing conflicting views on that because there are pros and cons to both of those approaches. That's why we've tended to focus in the submissions we've sent to this Climate Action Network Canada on the fundamental principles that need to underscore either approach.
Clearly the commitment made by the Prime Minister was to a cap, and it's difficult to see that the commitment could actually be achieved through a pricing mechanism, but this has clear advantages in terms of already being an existing mechanism in place that could perhaps be ramped up more easily, more quickly.
We've deliberately not made a final recommendation on that. There are a lot of complicated pros and cons in play with either proposal.
